Actually, there already has been some work in this direction, but MUSIC
et al are numerically very demanding (estimate autocorrelation matrix
AND do an eigenvalue decomposition). I'm therefore not convinced they
are massively useful for radio applications (in particular, with real
time constraints).

Something I'd like to have in the toolbox are cyclostationary spectral
estimation methods (FAM, SSCD etc), and I'm hoping to add these some
time soon (as in, this year).

Cheers,
